Traefik v1.7 + KeyCloak (RaspberryPi)

I have Traefik v1.7.24-alpine working on a raspberry pi 4, with duckDNS provider.

I also have KeyCloak container working (dedicated rpi-keycloak).

I want add a traefik-forward-auth, but i can't get it to wokr under raspberry. I want some container like funkypenguin/traefik-forward-auth working under armhf

Someone have on ARMHF something like that working???

I'm trying the same thing, but I'm also having difficulties. Have you got it working meanwhile? Also which keycloak and traefik images have you used?
